Thanks SES. I might try

I see your point. As the details of the patrol says that it took place in this area: 61*00' N, 4*00'E - 58*00' N, 4*30'E. Your map shows that this is a heavely covered area.
According to Frederik Meyer's book on RNoAF following several losses in the area, the squadron changes its patrolling practice. Perhaps they realised your point as well.
